After your conversion of the trees file (fondo largo) I could run the track fine in rFactor. The only problem is that this texture is no longer transparent. Now the tree wall is quite ugly because the sky isn't visible through the trees as before. Don't bother at this point, as we talked before, the first is to improve the track and after this, texturize the track using my real photos

This is usefull for begginers like me: You have to change the textures after convert them from JPG to DDS Even if BTB lets you to load JPG files when you want to you use your photos of the track objects, you have to convert them first to DDS

Yes, if you delete the sky in the trees texture, so that there are just the trees left, and then convert the texture to dds, an alpha channel is built automatically and that's what is important for the transparency of the tree textures sky. Afterwards just convert the dds to tga with dds converter and use it for krp

If, i learn how to make tracks, i will make all tracks in world i promiss! I have a lot of free time

Haha awesome

Don't worry I will help you with all your conversion problems as good as I can What is the big black area behind? Is it a wall without a texture?

I can't see any bigger mistakes at your screen, but maybe you did not name the track surface object correct in 3ds max and that's why the problems occur after importing. Did you follow the whole tutorial till the exporting step and did you understand every step?

If you rename the textures you perviously loaded into 3ds max with the whole track, don't change the name of the textures or the path where they are saved otherwise 3ds max won't find the textures anymore.
